Pinout

The CD4520BE is a dual 4-bit binary ripple counter IC. It contains two counters, each with a pin count of 16. The key pin functions are as follows:
1. Power Supply Pins:
- VDD (Pin 14): Positive supply voltage.
- VSS (Pin 7): Ground reference.
2. Counter Inputs and Outputs:
- A, B, C, D (Pins 1-4 for Counter 1, Pins 10-13 for Counter 2): Data input for the counter.
- Q0, Q1, Q2, Q3 (Pins 5-8 for Counter 1, Pins 15-16 for Counter 2): 4-bit output for each counter.
3. Control Pins:
- RESET (Pins 9 and 12): Asynchronous reset for both counters.
- CLOCK (Pins 4 and 13): Clock input for counting operation.
4. Carry Output:
- CARRY (Pin 11): Carry output for cascading multiple counters.
